kṣānti:

1. Endurance, tolerance, patience.

2. Receptivity, which is a form of prajñā. Two major meanings: (i) The cognitive ability to fully accept a truth/doctrine in advance, even before one has actually acquired the jñāna proper of that truth/doctrine. It is the moment immediately preceding that jñāna. (ii) The third spiritual attainment in the prayoga stage known as the four nirvedha-bhāgīya-s.
